Infura Development Tutorials, Guides & Insights

Before diving into code examples, it's important to understand the core differences between Etherscan and Infura.

• Etherscan:
• Primarily a block explorer and data provider. It offers read-only access to Ethereum blockchain data such as transaction histories, balances, token transfers, and more.
• Does not allow real-time interaction with the blockchain (e.g., sending transactions).
• Ideal for querying historical data and performing analytics on blockchain data.
• Infura:
• Provides full node access to the Ethereum network, allowing developers to interact with the blockchain in real-time.
• Supports read and write operations, such as sending transactions, deploying smart contracts, and interacting with dApps.
• Best for applications that require real-time interaction with Ethereum, such as decentralized apps (dApps).

In this tutorial, we will walk through how to use Ethers.js along with Infura to send Ethereum transactions and interact with smart contracts. Infura provides scalable access to Ethereum nodes, allowing you to interact with the blockchain in real-time without running your own node.

By the end of this tutorial, you will be able to send Ether, call smart contract functions, and deploy contracts using Infura as your provider.

In this tutorial, you will learn how to retrieve the balance of an Ethereum wallet using Ethers.js in a Node.js environment. We will cover two methods:

By the end of this tutorial, you’ll be able to query the balance of any Ethereum wallet and display it in Ether units.
